Drawing Instruments

Pocket Cases

This page displays the earliest sets in the mathematics collections. The coverings on the cases are sharkskin or tortoiseshell. Notable European makers crafted some of the instruments in these cases, including Pierre Martel, Michael Butterfield, Claude Langlois, and Thomas Rubergall. At least one of these sets is known to have been used in the early United States.

This wooden pocket case is covered with black sharkskin and lined with yellow paper. The set of brass and steel instruments includes: two drawing pens; a small drawing compass with a pen point; and large dividers with pen point and pencil point attachments.
